sdd

name	sdd
description	Use when the user wants to run the full Spec-Driven Development pipeline: Jira issue to spec, implementation, code review, test generation, and test review. Triggered by 'sdd', 'spec driven development', or a Jira issue key like SVY-12345.

SDD — Spec-Driven Development Pipeline (Servoy TiNG)

You are the orchestrator for the full SDD pipeline: PM Agent → Coding → Code Review → Test Gen → Test Review → Commit.

You collect output from each phase, show summaries to the user at approval gates, and thread context forward selectively to maintain isolation between phases.

Context isolation principle

Each phase runs as a task subagent with a fresh context. This prevents bias:

• The Coder only sees the spec, not the PM's internal analysis
• The Code Reviewer only sees the spec + actual code, not the Coder's reasoning
• The Test Generator only sees the spec + implementation, not review findings

You control exactly what information flows between phases via the task prompt.

Input

The user provides a Jira issue key or URL, optionally followed by extra context, e.g.: SVY-21080 some text meant to give more context about the case

Parse the first token as the issue key/URL. Everything after it is supplementary context provided by the user to clarify or augment the Jira ticket.

Record the issue key as ISSUE_KEY and the extra text (if any) as USER_CONTEXT.

---

Phase 1 — PM Agent: Jira → Spec

Read the file .opencode/skills/sdd/phases/pm-agent.md and pass its full content as instructions in a task prompt:

task(subagent_type='general', prompt="""
<contents of phases/pm-agent.md>

Issue: ISSUE_KEY
User context: USER_CONTEXT (or "None" if the user provided no extra text)
""")

The task's output will be the relative path to the spec file it created. Record that as SPEC_PATH.

HUMAN GATE — Spec approval

Use the question tool:

• Header: "Spec Review"
• Question: "Phase 1 complete. Spec written at SPEC_PATH. Please review it, then choose:"
• Options:
  • "Approve" — proceed to implementation
  • "Request changes" — provide feedback and I'll revise

If the user requests changes, apply edits yourself for minor revisions. For substantial rewrites, spawn a task(subagent_type='general') with the feedback.

Loop until approved.

---

Phase 2 — Coding: Spec → Implementation

Read .opencode/skills/sdd/phases/coding.md AND .opencode/skills/sdd/phases/project-context.md, then spawn:

task(subagent_type='general', prompt="""
<contents of phases/project-context.md>

---

<contents of phases/coding.md>

Spec file to implement: SPEC_PATH
""")

Important: Pass the project context + coding instructions + spec path. Do NOT include the PM agent's analysis, code samples, or reasoning — the coder should form their own implementation approach based solely on the spec.

Record the returned file list as CHANGED_FILES.

---

Phase 3 — Code Review

Read .opencode/skills/sdd/phases/code-review.md and spawn:

task(subagent_type='general', prompt="""
<contents of phases/code-review.md>

Spec file: SPEC_PATH
""")

Important: Pass ONLY the spec path. The reviewer must look at the actual code via git diff and source reading tools — not be influenced by the coder's context.

The task's response must begin with APPROVED or CHANGES NEEDED.

If CHANGES NEEDED:

Use the question tool:

• Options:
  • "Auto-fix" — spawn a coding agent with the review findings
  • "I'll fix manually" — pause until user says to continue
  • "Override" — proceed despite findings

If Auto-fix: spawn a task(subagent_type='general') with:

• The project context (phases/project-context.md)
• The spec path
• The review findings (these are explicitly passed — they're the "contract" for the fix)
• Instructions from phases/coding.md

Then re-run Phase 3. Repeat until APPROVED or user overrides.

---

Phase 4 — Test Generation

Read .opencode/skills/sdd/phases/test-gen.md AND .opencode/skills/sdd/phases/project-context.md, then spawn:

task(subagent_type='general', prompt="""
<contents of phases/project-context.md>

---

<contents of phases/test-gen.md>

Spec file: SPEC_PATH
""")

Record the output as TEST_FILES.

---

Phase 5 — Test Review

Read .opencode/skills/sdd/phases/test-review.md and spawn:

task(subagent_type='general', prompt="""
<contents of phases/test-review.md>

Spec file: SPEC_PATH
""")

Response must begin with APPROVED or CHANGES NEEDED.

If CHANGES NEEDED: spawn a fix agent with review findings + spec path, then re-run Phase 5. Repeat until APPROVED.

---

Phase 6 — Commit

HUMAN GATE — Final approval

Use the question tool:

• Header: "Ready to commit"
• Question: "All phases complete. Spec: SPEC_PATH, Implementation: CHANGED_FILES, Tests: TEST_FILES. Ready to commit?"
• Options:
  • "Commit now"
  • "Let me review first"

When approved, use git status to see all changes. Stage every file belonging to this feature.

Include: feature code, spec file, test files Exclude: opencode.json, .opencode/, unrelated files

Commit message format:

<JIRA_KEY> <short description from spec title> [ai]

- bullet points summarising what was built

Co-Authored-By: opencode <[e-mail]>

After committing, display the full commit message in a formatted block.

Error handling

• If any task returns a tool error, report it to the user and ask how to proceed.
• If the Atlassian MCP is unavailable, the PM phase will fall back to WebFetch.
• If a phase produces unexpected output, show it to the user via question tool.
